To trade goods or services with someone else without using money as exchange.
From Old French 'barater' meaning 'to deceive or cheat,' but in English it came to mean direct trade. The connection may be that early traders needed to haggle and debate the fairness of trades.
Before money was invented, barter was the only way humans traded, and it still works today—ancient Rome actually kept detailed barter exchange rates, and modern businesses still barter services instead of paying cash!
